Unable to import (encrypted) volume after upgrade

[petemounce]

I've just upgraded from 11.1-U6 to 11.1-U6.3 because of a USB drive failure on my mirrored freenas-boot. At the same time, my system-dataset (also on mirrored USB drives) failed. This has not been a great start to the year.

I have created a fresh freenas-boot pair (11.1-U6.3) on fresh USBs via a config backup (which I believe included the password seed). I have created a fresh system-dataset on a single USB (I have an SSD I intend to use for this purpose, _after_ I have recovered my main volume).

I have an encrypted volume, vol1, that I now cannot import after a reboot. AFAIK there's no issue with the disks themselves or the data stored within.

The UI tells me:

I have a monitor plugged in, and it tells me:

(Can't tell if there's a line break after the vol1 or whether that's the screen wrapping).

In a shell, basic diagnosis (and, I'm not highly familiar with which commands to run, but very willing to learn):

Based on some reading of the forum, it strikes me as likely that the IDs have changed, so I will need to do a permutation of

Code:

zpool import

.

The user-guide, 8.1.6, suggests the same - I should be importing a volume. When I go to that option, choose "decrypt disks" and proceed, the next page gives me no disks in the multi-select. Screenshot:

I'm sufficiently unfamiliar that I'd like to check how to proceed first, since clearly I don't want to hose my data.

On reading a bit further, I'm pretty sure that this is the pertinent bit of that manual section:

For security reasons, GELI keys for encrypted volumes are not saved in a configuration backup file. When FreeNAS® has been installed to a new device and a saved configuration file restored to it, the GELI keys for encrypted disks will not be present, and the system will not request them. To correct this, export the encrypted volume with Detach Volume, making sure that the options Mark the disks as new (destroy data) or Also delete the share’s configuration are not selected. Then import the volume again. During the import, the GELI keys can be entered as described above.
